ESDU 99013 gives data for fifteen liquid glycols@ glycerol@ aqueous solutions of five glycol compounds and aqueous solutions of glycerol. Experimental results drawn from the literature for each pure compound were fitted with a four-term polynomial equation in reduced temperature. The coefficients were also faired with changing molecular structure to ensure the best correlation not only for the individual compounds but also as members of their chemical series. The coefficient correlations also allowed values to be predicted for pure compounds for which no measured data exist. Experimental data for the aqueous solutions were similarly assessed@ and fitted using an equation for the thermal conductivity of mixtures. The equations were used to tabulate thermal conductivity values from the melting point to about 0.9 critical temperature in SI units at 10 K and 10 degree Celsius intervals. The likely uncertainties at various temperatures are assessed and are indicated in the tables. The critical point@ coefficients and sources of the data are given for each compound. The effect of pressure is briefly considered. Available as part of the ESDU Series on Physical Data.
